It will also be noticed by particular reference to Figure 8 that the spring plank 9 is recessed at the points 20 in order to enable it to snugly fit the truck frame.

' At the point 2lthe top bolster 10 is provided by preference with the ordinarywearate.

p It will be apparent from the foregoing that a truck frame constructed as herein illustrated and described is possessed of all of the practical advantages ascribed to my invention, and it will also be apparent that the truck frame is simple in construction and is well adapted to withstand the rough usage to which truck frames are ordinarily subjected.

I illustratethe truck frame as equipped with brakes, but this need not be described in detail inasmuch as they constitute the subject of my contemporary application of even date herewith. I would have it understood, however, in this connection that my present invention relates to the truck frame per se, and the said truck frame may be equipped with the brakes shown or with any other brakes, or the brakes may be altogether omitted from the truck frame without in volving departure from the scope of my present invention as claimed,

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the specific construction 1; In a truck frame, the combination of side members, a spring plank detachably interlocked with and supported by'said side members, a floating bolster yieldingly supported upon the saidspring plank and detachably interlocked with the side members, the said interlocking of the floating bolster being effected by T heads at the ends thereof disposed in correspondingly shaped recesses in the side members and the said interlocking of the spring plank being effected by pendent flan es at the ends thereof arranged exteriorly o1 portions of the side members and having recesses inwardly of the pendent flanges and at opposite sides of the plank for permitting the same to snugly .fit the truck frame.

2. Ina truck frame, the combination of side members, a spring plank detachably interlocked with and supported by said side members, and a floating bolster yieldingly supported upon the said spring-plank and detachably interlocked with the side mem- .bsrs, the said side members being provided with outwardly extending lugs, and the said spring plank being hooked over said ln s and having recesses adjacent its ends and at opposite sides thereof, for snugly fitting the truckframe.

In testimony whereof, I afiix my signature.
